spray foam behind drywall?


Is it possible to spray foam in a finished wall? Say by cutting a hole in the top of the drywall and spraying down? Or do I need to take all the drywall down? Or would another option be better (blown in insulation)?

I have 2 rooms that have crappy old insulation that I can pull out from the basement and wanna re insulate.

There are ways to do that, although dense packed cellulose would be far more cost-effective. If budget is not a concern, spray foam is great.

What type siding do you have? More often it's done from the outside.
It's not the best way to do it but better then nothing.
There working blind so there's going to be all kinds of way to have gaps behind that wall.

Either way, I'd fire-block the stud walls (upper ceiling level) from the basement ...
